4 Claims.

The present invention relates to window constructions and especially to a novel clip construction for facilitating; the assembly of the vertical and/or horizontal muntins of a window construction with the surroundingsash members or rails; The invention further comprehends a novel clip for securely attaching togetherthe vertical and horizontal muntinsincorporated in the window'assembly,

Another object of the inventiomis the provision of a simplified, imore eflective and more economical method and-mannerof attachmentof muntins to'the encompassing or associated sash rails than the prior: methods such as the morticed and tenonedsioints with the projected end of the tenon peened over; on t'hewelded joints, now in general use;

The invention further com-prehends' a novel method and manner of attaching muntins to the previously assembled surrounding sash rails as distinguishedv from the methods now in. use wherein the sash rails. and muntins are simultaneously assembled. This further permits assembly of the complete window" unit at the factory save for the: muntins. and permits the ready assembly of any desired muntin. design or arrangement. to meet the architectural style desired by the customer.

The novel invention further. provides amuntin assembly of increased strength by attaching the: vertical muntins-to bisectingi horizontal muntins, the latter extending in one piece from side rail to side. rail, instead of the" prior method of halving together the horizontal and vertical muntins.

Further objects are. to provide a construction of maximum simplicity, eflicien'cy, economy and ease of assembly and: operation, and such further objects, advantages and: capabilities as will later more fully appear and are inherently possessed thereby.

Referring more particularly to the drawings in which i disclosed an illustrative embodiment of the novel invention; a metal window A is shown as equipped with side rails I and 2,top rail' 3 and bottom rail 4; Secured to these rails are vertical muntins 5 and 6 and a horizontal muntin 1, the latter being shown in the form of a continuous member. primarily to a novel means and manner of assembling the vertical and horizontal muntinsto the sash rails.

The novel metal assembly clip 8 is provided with a pair of downwardly'or outwardly extending projections or prongs 9, and a pair of upwardly or inwardly spaced projections or legs Ill and I I. In order to assemble these c1ips', as' for example to the side rail t, the web i2 of this side rail is provided with spaced openings l3 for the reception of the projections 9 and the web M of the horizontal muntin 1 is notched at l5 for the reception of the leg l0, coped at l6 and I! to fit the contour of the rail l, and provided with an opening l8 for the reception of the leg II. The leg I0 is so spaced with respect to the The present invention relates this purpose, these projections or prongs 9 are;

turned or bent inwardly slightly as Figure 10.

shown in One end of the muntin] is droppedon clip I 8 previously inserted in rail, lfwith'the legs l and H entering notch I and opening 18, respectively. The clip is then brought up parallel to the muntin l and leg H is bent over but is not firmly set. The other end of the muntin -l is then dropped over a similar clip in the side rail 2 and, the sequenceof steps as outlinedabove is carried out with respect to that clip. When both-ends of the muntin-Tlxhave' been loosely secured in place as described above, the leg H will be firmly set as shown in Figures 2 and 6, and theleg iii/is thenbent' overv and firmly set, the operation being repeatedin connectionwith side rail 2.

The-projections and legsonthe clip and the opening l8 in the muntin l aresospaced that when :tl'ief; -leg. l is; sfirmly; set it will draw the muntin toward the? side rail 1' and zfirmly anchor and retain it in pl'acetmThe notch: l5 affords sufflclent clearance that the leg-all] is bent over to approximately a-al4'5" angle; before this leg touches the web of the muntin 1. This permits it to be set. without}. straining;- the; connection between theleg 'l I, and; the .web 14- of-' the. muntin.

Where the window is jp'rovidedwith vertical muntinsL5;and-.6;,each vertical muntin is provided with an opening =l9-and a notch at each endawhile the;.hor izontal-.muntin.l is provided withjtwozpairs of spaced-openings 2l,. the opening l9 being adapted to receive the leg I l vof the clip the notched portion ZOrbeing adapted to receive theqleg 1050f this .clip and each set or pair of spaced; opennigs, 2i; being .adapted to receive the projections or pr0ngss;9:ofthis ,clip. As will be; clearly; seen in] Figures "2v and-1'10,- the clips which attach adjacentverticalmuntins- 5 and 6 to the horizontal muntin l are IYGYGISGLiythG distance; between the pairs of;openi ngs 2I- being the thickness of the :webof the muntins: 5 and 6.

I From the above disclosure and the description inthedrawings, it; will =be apparentthat the inven on l emprehc pl la no el t l wi sembly in gwhich the vertical. and/or horizontal muntinsare secured to the surrounding sash rails in a more simplified, economical and effective th methods and manufacthe end of the muntin to be joined thereto having a notch and an opening spaced therefrom,

A metal window comprising surrounding sash rails, muntins adapted to be assembled in the windowframe to divide it into smaller opening s fand clips'for' assembling the muntins in the frame, the sash rails being provided with spaced openings and the end of the muntin to be attached thereto having a notch and an opening spaced inwardly from the notch, each of the clips comprising a metal member having spaced projecting prongsat one end adapted to be received and anchored in the spacedopenings in the sash rail, and a'pair of longitudinally spaced legs extending in a direction-opposite tofthe prongs, one of which legs is-adapted' to be received in the notch disposed in an end ofthe muntin and the other adapted tosbe received in the opening spaced inwardlyiromlthelnotch; the legs when deformed and bent?inwardly lrigidly anchoring the muntin: in the :side rail. 1 "5 l1 :7
